BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates generally to a modular transit system, and more particularly, to a modular transit system having a seating system that includes various interchangeable parts.

2. Description of the Background of the Disclosure

Development of seating systems in mass transit have traditionally involved a company pre-selecting a desired seating configuration and permanently installing the pre-selected configuration into a transit car or multiple transit cars. The procurement, design, implementation, and manufacturing process may take many years to complete so a company must plan ahead for the types of configurations that the company desires. If a company wishes to deviate from the pre-selected selections, the company must re-order the seating system and/or re-configure the car interior. Either of these options are extremely cost prohibitive.

The traditional seating systems suffer from many disadvantages. For example, once a transit car is designed and manufactured, the configuration of seating is limited to the original design. Still further, the transit company may have special ordered some unique configurations, but the transit car configurations are limited.

SUMMARY OF THE INVENTION

The present invention provides a modular transit system having a track system and/or modular seating that can be used to modify a transit car. The track system can support a variety of attachments to allow the transit car to be reconfigured.

According to one embodiment of the present invention, an adjustable furnishing system is de-mountably mountable to a generally vertical wall. The adjustable furnishing system comprises a mounting structure carried by the wall, a support frame having opposite first and second ends, and a furnishing carried by the support frame. The first end of the support frame releasably attaches to the mounting structure and the mounting structure supports the support frame in a cantilevered position with the second end extending outwardly from the wall with the furnishing carried thereon.

According to another embodiment of the present invention, a modular seat assembly is comprised of an elongate support spine extending longitudinally from a first end to a second end. A seat portion is connected to a front side of the support spine, and each of the seat portion and the support spine includes one of a complementary pair of interlocking portions. Additionally, the interlocking portion of the seat portion slides onto the interlocking portion of the support spine over the first end. The modular seat assembly further includes an end cap lockably disposed over the first end that prevents the seat portion from sliding off the support spine.

According to still another embodiment of the present invention, a method of assembling a modular seating system, including a seat portion attachable to a support spine, is disclosed. The method comprises the step of releasably attaching the seat portion to the support spine by sliding a projection of one along a channel of the other from one end of the support spine, wherein the projection interlocks with the channel. The method further comprises the step of locking an end cap over the end of the support spine to prevent the seat portion from dissembling from the support spine.
